I got this problem with animating, when I switch frames, the pose of reverts
Okay this is weird, I inadvertently solved the problem, it was apparently a glitch after all. What I did was changed the timeline to the idle animation to make sure it wasn't messed up too. And when I changed back to the timeline of the messed up animation it was working properly all of a sudden. To think I wasted a weak not getting my project done because of this problem and that was all I had to do.
